Camp Hathcock
From Halopedia, the Halo wiki
Camp Hathcock was a facility utilzed by the UNSC, and located on the northern continent of planet Reach. Nestled in the Highland Mountains, Camp Hathcock was a top-level retreat; heads of state, VIPs, and top brass were the facility's normal occupants, along with a division of veteran, battle-hardened Marines. After the battle of Sigma Octanus IV Spartan-117, Captain Keyes, and sever other members were debreifed here. Also the Spartans often ventured to the place during training.
